13. If the tool is not used for a long period of time,
the battery must be removed from the tool.
14. During and after use, the battery cartridge may
take on heat which can cause burns or low
temperature burns. Pay attention to the han-
dling of hot battery cartridges.
15. Do not touch the terminal of the tool imme-
diately after use as it may get hot enough to
cause burns.
16. Do not allow chips, dust, or soil stuck into the
terminals, holes, and grooves of the battery
cartridge. It may cause heating, catching fire,
burst and malfunction of the tool or battery car-
tridge, resulting in burns or personal injury.
17. Unless the tool supports the use near
high-voltage electrical power lines, do not use

SAVE THESE INSTRUCTIONS.
CAUTION:

Use of non-genuine Makita batteries, or batteries that
have been altered, may result in the battery bursting
causing fires, personal injury and damage. It will
also void the Makita warranty for the Makita tool and
charger.
Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. When not using the battery cartridge, remove
it from the tool or the charger.
5. Charge the battery cartridge if you do not use
it for a long period (more than six months).

► Fig.1: 1. Red indicator 2. Button 3. Battery cartridge
• Always switch off the tool before installing or
removing of the battery cartridge.
• To remove the battery cartridge, slide it from the
tool while sliding the button on the front of the
cartridge.
• To install the battery cartridge, align the tongue
on the battery cartridge with the groove in the
housing and slip it into place. Always insert it all
the way until it locks in place with a little click. If
you can see the red indicator on the upper side of
the button, it is not locked completely. Install it fully
until the red indicator cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not use force when installing the battery car-
tridge. If the cartridge does not slide in easily, it is
not being inserted correctly.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power to
extend tool and battery life. The tool will automatically
stop during operation if the tool or battery is placed
under one of the following conditions:
Overload protection
This protection works when the tool/battery is operated
in a manner that causes it to draw an abnormally high
current. In this situation, turn the tool off and stop the
application that caused the tool to become overloaded.
Then turn the tool on to restart.
Overheat protection
This protection works when the tool or battery is over-
heated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery
capacity gets low. In this situation, remove the battery
from the tool and charge the battery.
